Core Features
✅ Flexible pulse counting function Input pulse frequency: 0‑20 kHz; counting accuracy: ±1 pulse. Display range: ‑19 999 999 ~ 99 999 999. Counting modes: up‑count, down‑count, up‑down bidirectional counting. Scaling formula: Display Value = Pulse Count × Multiplier‑A ÷ Multiplier‑B. Configurable 0‑7 decimal places to convert raw pulses into length, yield and other engineering units. Supports power‑on preset value or power‑off count retention.
✅ Dual‑channel relay alarm outputs Two relay outputs (2 A 250 VAC). Alarm modes: high‑limit / low‑limit alarm. Hysteresis and alarm‑delay parameters are user‑configurable to avoid relay chattering.
✅ Dual isolated 16‑bit DA analog retransmission Two galvanically‑isolated analog output channels (isolation voltage: 2000 V AC), comprehensive accuracy 0.2 %FS. Signal types selectable: 0‑20 mA, 4‑20 mA, 0‑5 V, 0‑10 V, 1‑5 V, 2‑10 V. Each channel independently maps custom measuring ranges.
✅ Galvanic‑isolated RS‑485 Modbus‑RTU Supports read‑write access for total‑count values, alarm status, DI status, runtime hours and full instrument parameters. Seamless connection to PLC, HMI and host SCADA systems for centralized data acquisition.
✅ Sensor power supply & digital DI Built‑in 24 VDC / 30 mA excitation for external pulse sensors. Two DI digital inputs can be assigned for relay reset or direct relay drive. Accept NPN / PNP / complementary pulse‑input signals.
✅ Color LCD local operation Color LCD screen with real‑time date‑time stamp; four front‑panel keys for on‑site parameter setup.
✅ Wide‑range power options Power supply selectable: AC 85‑305 V or DC 24 V ±10 %. Max power consumption: 2.16 W. Operating ambient: 0 ~ +50 °C, ≤85 %RH non‑condensing. Input‑output isolation rating: 2000 V AC.
